Moving game saves ?

I was unsure wheteher to put it in here or wiihacking ?

OS downgraded to 3.2 with all the available Cios's
Soft modded ( Gamma 0.3 ) with Starfall running.
So far ALL games work

I bought wiifit and upon installing the disk, I was asked to create a save (as usual) when I agreed, the note about "memory full" came on screen.
I go to the Wii menu to move my game saves to the SD Card and click on
" move to SD". It thinks about it and then says " this file already exists cannot overwrite". But when I check the SD Card screen, all that is on there is the TP hack.
The only way to put the wiifit on was to delete a few older game saves.
Am I missing something really stupid here to allow me to save to the SD Card ?

Yes, that's what I did........
I just wondered if I had missed something, because I could not move the save to the SD card and I assume that I will have to start from the beginning of any game that I have deleted the save file for ?
